design flaws or problems with the product that were not anticipated. How do these
problems affect the innovating firm?

harm a firm significantly because consumers resist changing products for fear of
incurring high switching costs.

can enter the new market with a better product.

forgiving and are likely to remain loyal to the company and its products.
